TILL-LOCK.

QPBCIFICATION forming part of Letters Patent No. 345,125, dated July 6, 1886.

Applicatiomfiled May 4, 1886. Serial No. 20!,07'2. (No model.) I

To aZZ whom it may concern:

Be it known that I, J OHANN CARL FRIED- mcrr WILHELM DIESTEL, a subject of the German Emperor, and aresident of Altona, in the German Empire, have invented certain new and useful Improvements in Till-Locks, of which the following is a specification.

My invention relates to improvements in safety devices for drawers, preferably for shop counters or tables, to prevent them from being opened by thieves; and the object of the improvements is to facilitate the adjusting of such device to any size of counters or tables. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figures 1 and 2 are cross-sections of shopcounters provided with my improved safety device, the first showing the mechanism when arresting the drawer, and the second when the drawer is opened. Figs. 3, 4, 5, and 6 are de tailed views of the most important parts.

Similarletters refer to similar parts throughout the several views.

The drawer I) is provided at its hind part with a hook, a, into which engages a pawl, 0,

ports, 1". The rod may be raised by pressing down the treadle g, forming part of the twoarmed lever h h, to the hind arm of which the rod is hinged. The pawl c is arrested by a stop, (1, as soon as the noose c of the pawl rests thereon, thus preventing the latter from surpassing a given inclination, Figs. 3 and 4. When the drawer is pushed rearward, the hook a raises the pawl c'until it has passed the hind end of the pawl, which then drops down and engages behind the book a, thereby This arm is attached to a vertical rod, ff, guided in suitable suppreventing the drawer from being opened.

For opening the drawer the pawl a must he raised until the hook a may pass beneath it, whereafter the drawer can be pulled out.

The rodff, as well as the lever h h, are composed of two pieces each, of which one is hollow, thus allowing the other one to be adjusted therein. Set-screws e and i serve to fix the inner rods in their proper position, which de pends upon the size of the counter or table.

To maintain an equal proportion of the arms of lever h It by any difference in size of the counter or table, the pivots k of such lever, which rest in bearings m, are not fixed to the lever, but to a collar, k, which may be displaced on the rod h and arrested in the proper position by the set-screw Z, as shown by Figs. 5 and 6.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed,

I declare that what I claim as my invention 1. In safety devices for drawers, the combination of the hook a with the pawl 0, arm (Z, rod f f, and lever h h, substantially as set forth. I

2. In safety devices for drawers, the combination of the bearings m with lever h h, collar .k, and pivots is, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 5th day of April, 1886.
